Threshold spectra of SBS at a finite frequency mismatch of the interacting waves
08 April 2002
A problem of scattered radiation spectrum line width of stimulated Brillouin scattering (SBS) in plasma with two species of ions is considered. Threshold conditions, when SBS shifted frequency lines, which characterize the scattered radiation spectrum, are comparatively wide and are comparatively narrow, are defined. A possibility of existence of the scattered radiation spectrum with the frequency line width comparable to the ion-acoustic frequency is revealed. (C) 2002 Elsevier Science B.V. All rights reserved.
